Jeff Ravencraft, chairman of the USB Implementers Forum (USB-IF), referred to the possibility of speeding up the USB 3.0 transmission speed at the USB 3.0 Developers Conference that runs from May 20 to 21, 2009, in Tokyo, Japan.
Currently, the transmission speed of USB 3.0 is 5Gbps at a maximum, but its transmission protocol was designed to support the speed of up to 25Gbps, he said.
"The protocol itself can support the speed of 25Gbps," Ravencraft said. "But we don't know when USB 3.0 will reach that speed, of course."
Since the formulation of the USB 3.0 specifications, he has been saying that the 5Gbps transmission speed was decided to "meet the demand for the next five years." In other words, he indicated that the 5Gbps speed will be enough for the next few years but a higher transmission speed will be required in the future.
In consideration of the USB-IF's assumption, it is possible that new specifications of USB 3.0 will be discussed in about 2012 or 2013.
